Y Application filed August 1R, i884. (No model.)

To all whom it may concern:

Be itknown that I, EFFINGER' E.`WnIIrLn, of Eaton Rapids, in the county of Eaton and State of Michigan, have invented certain new -fwith the machine-frame.

and useful Improvements in Cultivators; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of the present invention is to provide a construction in culti vators whereby the dragfbars thereof, with the parts attached thereto, may be easily raised by the operator, securely held in theirelevated position withouteffort or attention on his part, and easily brought down to resume their work when desired, and also to improve the construction of cultivators in other particulars, as wil-l be hereinafter set forth.

AThe present invention consists in the matters hereinafter described,'and pointed out in the claims hereunto appended.

In the accompanying drawings, Figure 1 is a side elevation of a cultivator constructed according to and embodying the present invention, showing the drag-bars thrown down and the wheel removed from the side next the eye to more clearly show the construction of the parts. Fig. 2 is a plan of the same. Fig. 3 is a side elevation of the same, showing the drag-bars thrown up and one wheel removed, as in Fig. 1. Fig-4t is a plan in detail of a link, bar, or arm by which the drag-bar is attached to the axle. Fig. 5 is a side elevation of the same. Fig. 5a is an end View of the same. Fig. 6 is aside view of a modified form of the link or arm shownin Figs. 4 and 5. Fig. 7 is a partial section of the saine. Fig. 8 is a side view in detail of a portion of the drag-bar,showing'its connection with thelink or arm. Fig. 9 is a rear view-in detail of the link or depending arm that connects the front end of the drag-bar with the frame. Fig. 10 is a sideview ofthe dragbar,showing a modified form of devices connecting its front end Fig. Pl1 is a detail L'showing an arm or bracket used in the con- `Vstruction shown in Fig. l0. View 4in detail of the swivel-piece that eonneetsthe front end of the drag-bar with the Fig. 12 is a top linkfshown in Fig. 9. Fig. 13 is a top view y' in 'detail of a hook and anti-frietion roller used to connect the draft devices with the link of Fig. 4.

The cultivator herein shown belongs tothat class known as straddle-row 7 wheeled culti- Vaters, and is provided with an arched axle, A, wheels B B, and a tongue or pole, C, secured to the top of the arched portion of the aXle by a bolt, c, the ends of which pass through the pole and are held by nuts c'. Upon the said pole,- forward of the axle, is secured a cross-beam, D, which is connected near its ends with the axle by means of bracerods G G, which encircle the lower horizontal portion of the axle, and are bolted to the said cross-beam, so as to give a desired rigid connection between the tongue and the axle. The cross-piece Dis herein shown as bolted to the tongue and additionally secured thereto by diagonal braces d d.

The parts above mentioned form vthe frame of the maehine,to which the several operative parts are attached.

E E are drag-bars to which the tooth-bars F F, provided with flexible and oppositely curved and twisted teeth f, are attached by means of springs f f, the construction shown in the said tooth-barsand the teeth thereon being substantially similar to that set forth in A a patent heretofore granted to me. dles G G are also bolted to the drag-bars at g and further secured by braces g The han- The drag-bars are preferably constructed of two parallel horizontal iiat bars, e e, of iron, and held apart by'spacing-pieces inserted between them, and secured by bolts, as hereinafter more particularly described. The dragbars are, as shown, supported at their rear ends from the axle A by means of arms H, which are pivotally connected both with the axles and drag-bars so as to allow the rear ends of the latter a free upward and. forward movement, and said drag-bars are connected at their forward ends with the machine-frame by pivotal connections, permitting both a lateral and verticalfmovement of the rear ends of the bars, and also a bodily longitudinal movement thereof.

The arms H are, as herein shown, constructed to encircle the axle so as to rotate freely thereon,and preferably consist of two parallel parts, h h2, connected at their outer ends by rods h, which are parallel with-the axle, andas-'usually constructed are bolted to said arms at their ends, as shown. The said rods h may, of course,

The drag-bars, as before stated', are pivoted the rods h are made of considerable, length in order to allowl the drag-bars tosl-idefupon'the latteriwhen their rear ends arev movedl laterally inlthe .operation of the machine,.thef.said

rods'being insertedthrough apertures orslots' inthe drag-bars, which. slots are made-of suficient -le-ngthl to permit the rodk to move-longitudinally of.- the drag-bars when` the; latter Y are swung laterally, as above mentioned.

The links or arms I are, as herein shown, made-of invertedfU shape, a-nd arefpivotedto the -vbeaml D bytheihook-shaped bolts i; which prevent lateral motion of the li-nkbut permit their lower endstoswing freely ina longitudinal direction with: relation tothe frame.l

endsofztlientwo-bars eve, comprisingthe'fdragbar, astud, 737, y.connecting the said bar-sg.` and a-block-, i8, secured between the bars at,

nal movement thereof with reference to the l frame. The construction first described is, however, for several reasons, preferred.

By means of the devices described it is 0bvious that the rear ends of the drag-bars may be read-ily raised, the Varms H in such operation turning upon thel axle while the pivot- `rod` h is moving upward and forward until it has passedover the axle, when further forward movement of the bar is limitedby means of a suitable stopacting uponthe arm or dragbar, and' operating in connection withy the said arm tosustain-the-rear end-of thedra'g-barin an elevated: posi-tion. The said-` stop, asf-sho wn in Figs. 1,. 2, 3,t 5,` and 5, isI formedi by ai short rearward'l-ylbent arm, ha, upon the armzH, con.'- structed'. to-'encou-nter the vertical portionof the axle-arch, and, as shown-inL Fig... 10', is formedby the stud 7, which' limitsthey forward movement of: thefdrag-,bar by encountering .the bolt i5.

The. drag-ban is Obviously-heid inf. its-ei'epivot-rod h. whenL thev latter i's--inadvance-of thev` axle,A and said drag-bar may be readily tb rown downward into operative positionV by drawingfit baclrwa-rd until the saidpivot-rod is at thel rear of the axle, when lthebarfwill descend by itsr ow-nv weight.-v

The draft-gearin the machine shown@V preferably consists of a double-treeV or evener, J,

which isv pivoted tol the-tongue Grin front of the beamD, andc is-providedat kits-ends with two depenc-lingv loosely-hungbars, J', secured tothe evener. by eyeboltsj andfsingle-trees'Jz,

secured to the lower ends of the Ibars J. Draft-rods j are used to connect the bars J with the wheel-axles, said rods being provided with hooked ends constructed to enter one of a series of holes in the said bars, so thatthe rodsnnay be adjusted vertically on the bars. The barsJ are also preferably provided with two or more holes at their lower ends, so that the points of attachment of the singletrees thereto may be changed when desired.

As a preferred construction in the devices for attaching the draftgear in the machine constructed as above described, such devices are made as follows: The arm H has a pro` jecting part or arm, h3, extending out from the axle A in a direction opposite to that of the arm h2 and attached, as herein shown, to the part hof said arm. The arm hii has a slot, h4, formed in it, by means of which the draft-gear is connected with the axle. The position and direction of the slot h4 is such that a hook,vlink, or, as herein shown, an anti-friction pulley, h5, to which the draft-rod j isattached, will be drawn toward the outer end of the slot by the action of the draft when the drag-bar is in operative position, and the draft will, through this construction, produce a downward pressure on the drag-bars, so as to force the cultivator-teeth into the ground, this downward pressure obviously being greater in proportion to the distance of the pulley h5 from the axle.v The pulley h5 may be prevented from moving out to the end of the slot h* when the full pressure downward on the teeth is not required by a bolt or stop pin, hs, inserted in one of the holes, h, in the arm h3, as shown in Figs. 5 and 6. When the drag-bars are thrown up to carry the teeth free from the ground, and the arm H swings upward around the axle A, the pulley h5 is caused to slide to the inner or upper end of the slot It4 by the action of the draft, and said slot being, asshown, extended so thatits upperend is above the axle when the parts are in the position mentioned, the action of the draft will, when the arm H is in its elevated position, keep it there, and thus prewent the teeth from resuming their operative position.

Instead of the slot h, a T-shaped rib may be formed on the arrnl, and the hook orlink hT may be furnished with two pulleys to run on the inner surface of the' head of the T, as is clearly shown in Figs. 6 and 7; but the construction iirstdescribed is preferred.

The particular draft-connections described are obviously not necessary to the successful operation ofthe machine constructed in other respects as above set forth,and the arm h3 may therefore be dispensed with and the draftrod connected with/the axle by means of a pivoted connecting-piece, j?,as shown `in Fig. l0.

By means of the vertical adjustment of the forward ends of the draft-rodsupon the bars J the direction of the draft with relation to the arm H and axle A may obviously be `tioned for securing them tothe bars.

the draft when the dragbar is in operative position may be increased or diminished as desired. The drag-bar is, as herein shown, bent at'e3 to allow the pivot-rod to descend to a position horizontally in the rear of that of the axle on which the arm H swings, and a brace or strengthening piece, e4, is bolted to the forward end of the dragbars, extends over the bent portion,`and is secured at its rear end by the bolts which fasten the cross-pieces F to the dragAbars.

In the construction shown the bars or plates e e,comprising the dragbars,are connected so as to give the desired rigidity to the dra-gbars by means of the parts inserted between the said plates,consisting of the swivel-pieces i?, the thinlbles e e', the ends of the cross-bars F F2, and the ends of the braces g', and the several bolts passing through the parts men- The springs f are, as shown, attached to the cross-pieces F F2 by means of plates f2., reccssed upon their upper and lower faces to rec eive the'ends of the cross-pieces and springs and bolts passing through the several parts mentioned.

Inasmuch as the draft-rod j may be connecte'd with the .arm h3 of the arm H otherwise than by a sliding connection, as herein shown,with the same novel result offorcing the rear end ofthe drag-bar downwardly by the K action ofthe draft upon said arm h3, my invention,as it relates to the parts mentioned,is not limited to such sliding connection between the draft-rod and the arm. A construction of the parts may be used, for instance, in which the arm It is provided with an eye at-itslower end,into which the draft-rod is hooked, a second eye or aperture, in case such construction ICO is used, being preferably located upon the,A said arm in posit-ion corresponding with the inner orupper end of the slot h4, into which the draft-rod may be hooked when thedrag-bar is raised,in order to prevent the forward pull of the draft-rod upon the arm h3 from throwing the arm H backwardly, and thus causing said drag-bar to fall.

A principal feature of improvement in the machine herein set forth is that wherein ,the drag-bar is pivoted to the machine-frame at its front end by devices permitting Aboth a lateral and vertical movement of its rear end,

and a crankarm pivoted to the frame and having laterally-sliding connections with the bar is adapted to operate upon the latter at the rear of its pivotal point. The improved result due to this feature of construction arises from the fact that the force for lifting and depressing the drag-bar is applied to the latter at its rear portion, whereby a much greater effect is produced by the spring or draft in lifting the bar or in thrusting the teeth into the ground than when the devices for lifting and depressing the bar are applied at its point of pivotal connection.

As far as the feature of operation above mentioned is concerned, it is obvious thatthe IIO sameeffect may be-produced when-theV dragbar is pivoted to a part of the frame other than-the aXle, and when the connecting deyvices, instead? of permitting bcdiliy longitudinal movement in the-drag-ba-r with reference tov the pivotal aX-is of the crank-arms, are adapted to permit a lateral and-verticalmovement in the-rear end only; and the free end-of thecrank-arm is connected With'the drag-bar by means adapted to permit the crank-pinto move both longitudinallyand laterally with reference'- to the said drag-bar, as is illustrated, for instance, in the machine shown inE an alpplieation filed by me uponthe 18th day of Oc'- tober, 1884, in which the same general features of construction above mentioned' are present.

Theli'mportant function of thespring, which, as 4herein shown', operates to'- draw the dragbarforward is by its action upon-the cra-nkarm to-assistthe' latter in lifting the-drag-ba'r.

They same result may obviously be accom-I plishe'd -byaconstruction of the parts-in whichy the sp ri'ngis connected directly wit-l1 the crank'- arm, as is shown inthe machine described in the'patent above referred to, instead of operating through the medium of the longitudinallymovaole drag-bar, as herein shown.

An important advantage is gained by the construction in whichV the' drag-barsare longitu'dinally movable and are pivoted upon' the axlefasherein-shown, for the reason that when the drag-bars are' supported in-this manner and are thrown' upwardly and forwardly, their centerof gravity is moved forward with reference to thevaxl'e so as'to bring al preponderance of Weight forwardof the'axle, and thereby prevent any tendency of the machine' to tip over' backwardly when the teeth are raised ,from the ground.

inasmuchl as the severalV general features of improvement abovel stated may beappliedl` .equally well to'cultivators other than strad- .dle-row,.such as herein; shown, theappen'ded claims' arey intended to cover said features of improvement as applied? toany form-.of maf chine in connection with which they are capable of use.
